Applications
The LM1086IS-5.0/NOPB is widely used as a post-regulator in embedded systems, microcontroller boards, and FPGA power supplies where a clean, stable 5V rail is required. Its low-dropout characteristic makes it ideal for battery-powered devices and automotive accessory circuits that must extract maximum run time from a supply only slightly above 5V. It is also commonly deployed in industrial instrumentation and telecom line-cards to power logic and sensor subsystems from higher-voltage bus rails.

Frequently Asked Questions
What is the output voltage and maximum output current of the LM1086IS-5.0/NOPB?
The LM1086IS-5.0/NOPB provides a fixed 5.0V output with a maximum continuous output current of 1.5A. The dropout voltage is typically 1.3V at full load, meaning the input supply must be at least 6.3V to maintain regulation.
What package does the LM1086IS-5.0/NOPB come in, and what are the thermal considerations?
It is housed in the TO-263 (D2PAK) surface-mount package (JESD-30 code R-PSSO-G3), which provides excellent thermal dissipation through the exposed tab soldered to the PCB. For full 1.5A operation, adequate copper pour or an external heatsink area is recommended to keep junction temperature below 125°C.
Can the LM1086IS-5.0/NOPB replace an LM7805 or LM317 in existing designs?
Yes, the LM1086IS-5.0/NOPB is often used as a drop-in upgrade over LM7805-style regulators because its 1.3V typical dropout is far lower than the LM7805's 2V, allowing operation from lower input voltages. Compared to an adjustable LM317, the LM1086IS-5.0 offers a fixed, pre-set 5V output without external resistor-divider components, simplifying BOM and improving output accuracy.
What input voltage range is supported, and is there a maximum input voltage limit?
The recommended input voltage range is 6.5V to 29V, with an absolute maximum of 29V. Exceeding 29V risks permanent damage to the device. A 100µF output capacitor with low ESR is recommended for stability.
Where can I buy the LM1086IS-5.0/NOPB and what is the typical price?
The LM1086IS-5.0/NOPB is available from FindMyChip starting at $1.62, with global stock from authorized distributors. Submit an RFQ on the product page for volume pricing and expedited worldwide shipping.
